COMBINED CARBURETED -AIR AND VAPOR BURNER.

SPEGEFECATJON forming-part of Letters Patent No. 676,522, dated J' une 18, 1901.

Application filed June 16, 1900 To all whom it may concern:

Beit known that I, EUGENE P. WOILLARD, a citizen of the United States, residing at Vest Palmb'each, in the county of Dade and State of Florida, have invented a new and useful Combined Carbureted-Air and Vapor Burner, of which the following is a specication.

My invention is an improved combined car y bureted-air and vapor burning lamp, one object of my invention being to provide a vaporburning lamp with means for carbureting air and burning the same, so that the lamp may be instantaneously lighted Without the necessity of iirst'heating the burner.

A further object of my invention is to effect improvements in the means for converting gasolene or otherliquid hydrocarbons into vapor to be consumed in the lamp.

lVith these and other objects in view my invention consists in the peculiar' construction and combination of devices hereinafter fully set forth, and pointed out in the claim.

In the accompanying` drawings, Figure 1 is an elevation, partly in section, of a combined carbureted-airand vapor burner lamp and apparatus embodying my improvements. Fig. 2 is a detail sectional view of the mixingchamber. Fig. 3 is a detail sectional view of one of the vaporizing-coils and its inclosing cone.

In the embodiment of my invention here shown the pipe 1, which is adapted for use both as av supporting-standard and as a carbureted-air pipe, is provided at its upper end with a plate or flange 2, whereby it may be attached to a ceiling or other suitable overhanging support. A mixing-chamber 3 communicates with the lower end of the said pipe l, and from the said mixing-chamber depends an expansion-chamber 4, Which is tubular in form. A tube 5 leads from the expansionchamber to a burner 6, which is a Bunsen burner of the usual form. As here shown, the lamp is provided with two burners, and a flexible joint '7 is formed between the inner ends of the pipes 5 and the lower end of the tubular expansion-chamber 4E, for a purpose presently stated herein. The mixing-chamber 3 is provided with air-intakes 8 and with dampers 9 for opening and closing said airintakes. Said dampers may be operated by any suitable means, as by handles 9", (indi- Serial No, 20,559. (No model.)

cated in Fig. 1,) and which may be of any preferred construction. In the pipe 1 is a valve 10, and in the lower end of said pipe Where it communicates with the mixing-chamber is a tip 11. Apipe 12 leadsfrom the top of a tank or reservoir 13 for gasolene or other liquid hydrocarbon vapor to the pipe 1. An airpump 14E has a tube 15, which leads to the said tank or reservoir 13 and has a leg 16 depending therein. A tube 17 leads from the said tank or reservoir at a point near the bottom thereof and is adapted to convey gasolene therefrom to vaporizing-coils 13, which are located above the burners and are adapted to be heated thereby. Said vaporizing coils communicate with the mixing-chamber, as at 19, and needle-valves 2O are provided, which serve to regulate the supply of vapor to the mixing-chamber and to cut off the sup- ,ply thereof, as may be desired. The vaporizing-coils are provided with interior cores 2l, made of spirally-twisted Wires,Which,While filling the said coils, form spirally-disposed grooves or channels which admit of the passage of the vapor through the vaporizing-V coils. The said twisted Wires being conductors of heat coact with the heated vaporizingcoils in the conversion of the hydrocarbon liquid into vapor and increase the eftioiency of said vaporizing-coils.

The operation of my invention is as follows: Air being pumped into the tank 13, the same becomes carbureted as itrbubbles up from the lower end of the leg 16 through the body of the gasolene in the tank, and the valve 10 being open the carbureted air under pressure passes through the pipe 12 to the pipe 1, and through the tip 11 into the mixing-chamber 3, and thence through the tubular expansion-chamber et and pipes 5 to the burner 6, Where it may be ignited by a match and burns instantly. The heat from the burners speedily raises the temperature of the vaporizing-coils to such a degree as to cause the latter to convert gasolene fed thereto into vapor. When the vaporizing-coilsare thus eliciently heated, the valves 2O are opened and the dampers 9 opened, and the valve 10 being closed gasolene from the tank or reservoir in passing through the Vaporizing-coils is converted into vapor, which is supplied to and consumed in the burners, the

earbureted air being used only 4for a long enough period to heat the Vaporizing-coils. The air-intakes 8 and dampers 9 regulate the admission of air to the carbureted air in the mixing-chamber.

When it is desired to use carbnreted air solely as the illuminant, the burners 6, by reason of the joint 7, may be turned at right angles to the position indicated in Fig. 1 with relation to the Vaporizing-eoils, so as to move the burners from their position under said Vaporizing-coils.

derstood.

Having thus described my invention, I claim- The combination of a mixing-chamber having air-intakes and dampers to elosethem,

I employ covers 21, whichk are conical in form, on the vaporizing-coils tov concentrate the heat therein, as will be un-A 'my own I have hereto axed my signature in the presence of two Witnesses. Y Y
